CONDITIONING YARN, THREAD AND THE LIKE Filed Dec. 16, 1946 latented May 27, 1952 Charles F. Duiken,Y Montclair, Helmuth. (Lf-Sonntag, Newark, and George'' Westwater, V Irvington, N.' J.; Asaid Westwaterfand saidV Sonntag assignors to said:Dulken Application December 16, 1945, Serial No.y gigli f' Claims. (Cl. A299-885) The present invention relates to a method and meansl for applynga textile material conditioning or dyeing liquid to the roll which is used in conventional winding machinesfor rotating the package While it forms on the yarn holder.

An objectof the invention'is the provision 0f a method as aforesaidcharacterized in thatthe Vliquid is'iirst vatomized by pressure reductionin a nozzle, and the resulting mist iscaused to form a sheetlike spray of mist which isjdirected onto the roll, on ywhich the spray isrconverted into a thread orjthe like while it forms the package.

Arfurtherobject of theinvention isvthe provision ofl a method 4as,.described supra in which thez liquid isdrawniroma source of supply in a substantially continuousstream all of which is' altoxnized or, transformed into a fog or mist, and a portion of said mist is caused to ow and be sprayed on the roll inthe form of sheet, while the other portion of the liquid is returned tothe source in asubstantiallyV continuous iiow.

Another object of the invention is the control, in a uid applicationsystempfthertype described supra,l of the quantity ofV the portion caused to form ajsheetlike spray by controlling the amount of iiuid returned to the source.

A further `object of the invention is the (control of the thickness of the sheetlike mist spray and ,thereby of the density of the mist.

object of the inventioneis the provisionof methods asjdescribed supra comprising the step of; returning all yof 'the atomized liquid tovthe source in case formation of the package is interrupted, which stoppage is caused in conven- `film which is wiped from the roll by the yarn or tional winding machines for example upon breakage of a thread.

It is an object of the present invention to-provide a method of the character describedwhich primarily utilizes an existing manufacturing Loperation for assuring the new result.

Another object of the invention resides in the provision of an apparatus to carry out the above method and which apparatus forms an attachment to conventional winding machines.

A further object oi the present invention is the provision of an apparatus producing the new result which apparatus, except for a valve or gate means which is automatically closed in dependence on a stoppage of the winding operation, has no moving parts.

An object of the present invention is the provision of an apparatus which has no parts which move during normal operation of the device.

Further and other objects of the present invention will be hereinafter set forth in the accompanying Aspecificationy and Aclailns andl shown. in the drawings which,A by way of illustration, show what we now consider tobea preferred embodiment of our invention.

The portion ofthe mist which does not escape into chamber l2 leaves chamber 4 'throughSlOt "i3 from which it is returned to reservoir`2 .through conduit I4. The quantity of n uidjrfeturned through conduit .I4 depends on the position of valve 'L l Valve 1 is normally held open 4by a weight. .l5 connected'to onev arm of lever I'B whichV is yconnected to hinge rod 8 and extends substantially transversely thereto. The extent of opening of valve 'l depends on the setting of screw I1 against the lower end of which the ap 1 is pressed by the action of weight I5. A spring may be used instead of weight I5 without changing the result. To the far end of lever I6 a link member i8 is connected which is linked to the conventional trip mechanism vof the existing winding machine in connection with which the attachment according to the invention is used. These trip mechanisms are usually responsive to a failure in the yarn or thread to be wound and disconnect the drive roll I9 from the package. In this case moistening of the roll I9 is undesirable and link i8 pulls on lever I6 and closes valve 1.

The mist entering chamber I2 broadens out due to the triangular conguration of the casing of the new device and leaves chamber I2 through slot 20. The width of this slot can be adjusted by proper positioning of iiap 2| which is hinged to an end wall member 22 of chamber I2 and extends through the width of the wide end of chamber I2. Flap 2i is held in open position by means of spring 23 and abuts the end of a set screw 24. The fog or mist escaping through slot has the form of a sheet which is sprayed onto roll I9 and forms thereon a film which is picked up or wiped off by the thread or yarn while it is wound on the package.

It is advisable to mount the applicator or spray device in slightly inclined position on the winding machine, with the discharge slot higher than the slot or opening through which excess iiuid is returned to the source. This assures that any liquid which is insuiiiciently atomized flows on the bottom of the applicator back to the opening I3 through which it is returned to the source of supply, and a homogeneous mist of uid leaves the applicator, and dripping from the discharge slot 20 is avoided.

While we believe the above described embodiment of our invention to be a preferred embodiment, we wish it to be understood that We do notdesire to be limited to the exact details of design and construction shown and described, for obvious modications will occur to a person skilled in the art.

We claim:

1. An apparatus for producing a iilm of yarn conditioning liquid on the roller driving the package in a yarn winding machine, said apparatus comprising, in combination, a flat substantially triangular case having a substantially triangular bottom wall and a substantially triangular top wall parallel to said bottom wall, an atomizing nozzle terminating in a corner of said case and delivering a spray jet of liquid into the case, said case having a side Wall disposed opposite said nozzle and extending at substantially a right angle to said bottom and top Walls and comprising slot; means for discharging a sheet of vaporized liquid from said case.

2. An apparatus as defined in claim l, said side wall comprising a stationary wall portion having an edge and being disposed transversely of the iiow of the vaporized liquid and a flap member having a surface portion disposed substantially parallel to the iiow of the vaporized liquid and in juxtaposition to said edge for forming a slot opening therewith.

3. An apparatus for producing a nlm of yarn conditioning liquid on the roller driving the package in a yarn winding machine, said apparatus comprising, in combination, a iiat substantially triangular case having a substantially triangular bottom wall and a substantially triangular top wall parallel to said bottom wall, an atomizing nozzle terminating in a corner of said case and delivering a spray jet of liquid into the case, said case having a side wall disposed opposite said nozzle and extending at substantially a right angle to said bottom and top walls and comprising slot means for discharging a sheet of vaporized liquid from said case, said case being in inclined position and said slot means being elevated relative to the corner Where the nozzle is located, an outlet for the liquid disposed at the lowest point of said case. and a gate in said case disposed in the path of the atomized liquid between the nozzle and the slot means, said gate being swingably connected with said case about an axis parallel and adjacent to the top wall and adapted to depress the stream of atomized liquid toward the bottom wall.

4. An apparatus as defined in claim 2, said flap member being svringably connected with said case to swing about an axis substantially parallel to said Wall portion and to the top and bottom walls of said case.

5. An apparatus as dened in claim 3, comprising pivot means extending from the outside into said case and swingably supporting said gate, actuating means connected with said pivot means for operating the gate from the outside of the case, adjusting means extending through said top wall into said case and abutting said gate for limiting its opening, and means connected with said actuating means tor yieldingly pressing said gate against said adjusting means.
